I have an important update.
I received the Certificate of Conformity from Land Rover today for my 2000 4.0 P38.
According to the CoC the emission values are:
CO: 0.698 g/km
NOx: 0.051 g/km
HC: 0.131 g/km
HC + NOx: 0.182 g/km
Apparently Euro 4 has the following requirements:
CO: 1.0g/km (pass)
THC: 0.10g/km (fail, although not sure if it can be compared with HC or not/)
NOx: 0.08g/km (pass)
So it appears to not be Euro 4 compliant as it fails for HCs.
However, and this is important. ULEZ only care about NOx. Nothing else.
The ULEZ standards are:
https://tfl.gov.uk/modes/driving/ultra-low-emission-zone/ways-to-meet-the-standard
- Euro 3 for motorcycles, mopeds, motorised tricycles and quadricycles (L category)
- Euro 4 (NOx) for petrol cars, vans, minibuses and other specialist vehicles
- Euro 6 (NOx and PM) for diesel cars, vans and minibuses and other specialist vehicles
So, my old V8 appears to be ULEZ compliant after all.
I've just sent of my V5 ad CoC to TFL.
They said they need a signed letter form the manufacturer, but I will try my luck with their email for now.
I'll let you know how it works out.
